Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer production, in particular to a drying device for slow-release fertilizer production. Background Art

[0002] Organic nitrogen compound fertilizers that can be decomposed under biological or chemical action are usually called slow-release fertilizers. Slow-release fertilizers need to be dried during production to ensure the fertilizer effect. The rotary drum dryer is a commonly used drying equipment, which uses a rotating drum to dry the material. A shoveling plate is provided inside the drum to scoop up the internal material to disperse the material and improve the drying efficiency. However, the shoveling plate in the existing drum is generally fixed and cannot be adjusted. The amount of material scooped up by the shoveling plate each time is fixed and cannot be adjusted according to the amount of material to be dried and the production situation, which is not conducive to the dispersion of the material, affects the drying effect, and has poor flexibility in use. Therefore, based on the above technical problems, it needs to be improved. Utility Model Content

[0026] Example

[0027] See also Figure 1-6A drying device for slow-release fertilizer production comprises a drying cylinder 1 which is arranged obliquely, a higher end of the drying cylinder being rotatably connected to a feed cylinder 2, and the other end being rotatably connected to a discharge cylinder 3, the feed cylinder 2 being provided with a feed hopper 4 and an exhaust port, the discharge cylinder 3 being provided with a discharge port 5 and an air inlet, the drying cylinder 1 being connected with a driving mechanism and a supporting mechanism, a drying inner cylinder 6 being fixedly connected inside the drying cylinder 1, a plurality of shoveling plates 7 being evenly arranged in the circumferential direction inside the drying inner cylinder 6, the shoveling plates 7 being slidably matched with the drying inner cylinder 6 in the radial direction, one end of the shoveling plate 7 being connected with a shoveling bending portion, the other end extending into the annular chamber formed by the drying cylinder 1 and the drying inner cylinder 6 and being connected with an adjusting rod 8, and the adjusting rod 8 being connected with an adjusting mechanism.

[0028] In this embodiment, the feed cylinder 2, the discharge cylinder 3, the drying cylinder 1, and the drying inner cylinder 6 are all coaxially arranged, and the feed cylinder 2 and the discharge cylinder 3 are both connected to the interior of the drying inner cylinder 6; four copying plates 7 are provided.

[0029] A groove is provided on the wall of the drying inner cylinder 6 for the copying plate 7 to pass through, and a through hole is provided on the wall of the drying cylinder body 1 for the adjusting rod 8 to pass through. Sealing gaskets 9 are provided on the inner walls of the groove and the through hole to ensure the sliding sealing cooperation between the copying plate 7 and the drying inner cylinder 6, and the adjusting rod 8 and the drying cylinder body 1.

[0030] The driving mechanism is used to drive the drying cylinder 1 and the drying inner cylinder 6 to rotate. The feed cylinder 2 and the drying cylinder 1, and the discharge cylinder 3 and the drying cylinder 1 are all in rotational sealing cooperation. The rotational sealing structure is a prior art and will not be described in detail. When the drying cylinder 1 rotates, the feed cylinder 2 and the discharge cylinder 3 do not rotate, which is convenient for feeding and discharging. The supporting mechanism is used to support the drying cylinder 1.

[0031] Working principle: The driving mechanism drives the drying cylinder 1 and the drying inner cylinder 6 to rotate, the material enters the drying inner cylinder 6 through the feed hopper, and the hot air enters the drying inner cylinder 6 through the air inlet. The material in the drying inner cylinder 6 moves downward under the action of gravity and contacts with the hot air in the reverse flow, thereby achieving drying; during the drying process, the lifting plate 7 rotates with the drying inner cylinder 6, and continuously lifts and lowers the material, pours and disperses the material multiple times, so that the material is spread on the entire cross-section of the drying inner cylinder, improves the filling degree of the drying inner cylinder 6, and increases the contact area between the material and the hot air, thereby improving the drying efficiency. After drying, the material enters the discharge cylinder and is discharged through the discharge port.

[0032] The position of the lifting plate 7 can be adjusted along the radial direction of the drying inner drum 6 by the adjusting rod 8 to change the amount of material picked up by the lifting plate 7 each time, so as to meet different usage requirements, improve usage flexibility and ensure the material drying effect.

[0033] Specifically:

[0034] When the amount of material in the drying inner cylinder 6 is small, if the amount of material picked up by the copying board is too large, the material will accumulate on a certain copying board 7, which is not conducive to the dispersion of the material. At this time, the copying board 7 can be moved outward to reduce the length of the copying board 7 inside the drying inner cylinder 6, thereby reducing the amount of material picked up by the copying board 7, so that the material is dispersed on multiple copying boards 7;

[0035] When the amount of material in the drying inner cylinder 6 is large, if the amount of material picked up by the copying plate is too small, the material will accumulate at the bottom of the drying inner cylinder 6, which is not conducive to the dispersion of the material. At this time, the copying plate 7 can be moved inward to increase the length of the copying plate 7 located inside the drying inner cylinder 6, thereby increasing the amount of material picked up by the copying plate 7 and avoiding material accumulation.

[0036] This embodiment further includes a base, and the feed cylinder 2 and the discharge cylinder 3 are both fixed on the base.

[0037] The driving mechanism comprises a driving gear and a driven gear 10 . The driving gear is connected to a driving motor. The driven gear 10 is connected to the drying cylinder 1 and meshes with the driving gear.

[0038] The supporting mechanism comprises a connecting wheel 11 and two supporting wheels 12 which are respectively arranged on both sides of the connecting wheel 11 and are tangent to the connecting wheel 11 .

[0039] In this embodiment, the driven gear 10 and the supporting roller 12 are rotatably connected to the wheel frame respectively, and the wheel frame and the driving motor are both fixed on the base.

[0040] The driving motor starts and drives the drying cylinder 1 to rotate through gear transmission.

[0041] There are two groups of supporting mechanisms for supporting the drying cylinder 1 to ensure its balance.

[0042] The adjustment mechanism includes a connecting flange 13 and an adjusting ring 14. The connecting flange 13 is fixed to the drying cylinder 1. An arc-shaped long hole 15 coaxial with the drying cylinder 1 is provided on the connecting flange 13. The adjusting ring 14 is coaxially sleeved on the outer side of the drying cylinder 1. An arc-shaped sliding groove 16 is provided on the adjusting ring 14 corresponding to each adjusting rod 8. A sliding rod 17 is slidably provided in the sliding groove. The sliding rod 17 is connected to the adjusting rod 8. A connecting hole 18 is provided on the adjusting ring 14 corresponding to the arc-shaped long hole.

[0043] In this embodiment, the slide groove extends from the edge of the adjustment ring 14 to the center.

[0044] When adjusting the copying plate 7, the adjusting ring 14 is rotated, the slide rod 17 slides in the slide groove, and the copying plate 7 is driven to radially displace through the adjusting rod, thereby realizing the position adjustment of the copying plate 7. After the adjustment is completed, the adjusting ring 14 and the connecting flange 13 are connected by connecting bolts penetrating the connecting hole and the arc-shaped long hole.

[0045] The adjustment mechanism of this embodiment can perform linkage adjustment on multiple copying plates 7 to ensure the consistency of the amount of material picked up by each copying plate 7, which is beneficial to the dispersion of the material, and also simplifies the adjustment operation and improves the convenience of use.

[0046] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments.
